Since using this app, I have definitely noticed a difference in my sleep. I wake up feeling energized, refreshed, and less cloudy in the mornings. I love how it adds the amount of time it takes for me to go to sleep within the sleep cycle calculation. This app also sets an alarm directly to the default alarm app on my phone at the press of a button. There are no ads and it has a simple, easy to follow format. This app was definitely worth the download! Loved it!

I used to use this app every night and it was perfect. The old app would take you to the clock app so you could verify the alarm. Today I didn't get an alarm because the app didn't send my alarm time (maybe I didn't set it right) and didn't take me to the clock app to verify. My fault for not double checking, but the old version was much better. Thanks to the Developer for fixing the issue quickly! (I still like the old UI better, but the app works great)

This app may not seem as much but it does help to show a layout of how many hours you could sleep from let's say at the current time you're checking the app on. Even better, helps to show what time you could sleep as well as the hours to the time you choose to wake up. Unless you're unsure about how long you sleep because your daily routine is thrown off say for morning college courses, then this could help you to be sure of how to get enough sleep for those certain days.
